Telco-Initiated Line Loopback

The Hotwire 8784 Termination Unit supports line loopback as specified in AT&T TR 54016, AT&T TR 62411, and ANSI T1.403. A Telco-initiated line loopback loops the received signal on the DSX-1 interface back to the DSX-1 interface without modification. Framing, CRC, and FDL bits are returned unaltered, and no BPVs or other line coding errors are removed.

Telco-Initiated Payload Loopback

The Hotwire 8784 Termination Unit supports payload loopback as specified in AT&T TR 54016 and ANSI T1.403. A Telco-initiated line loopback loops the received signal on the DSX-1 interface back to the DSX-1 interface. Framing, CRC, and FDL bits are regenerated at the point of the loopback, and BPVs are removed.
